Answer 1

If you shoot in low-lighting situations, yer bound to come across this problem called Digital Noise (often called Blue Channel noise)

1. Open a photo that conatins the digital noise you want to remove.
2. Go under the Filter Menu - Noise - Reduce Noise // Click on the Plus (+) sign about four or five times to zoom in.
3. Try cranking the strength up to 7 or 8. // Set the Preserve Detail slider between 40% and 50%. // Set the Reduce Color noise to about 65% (drag to the right for more reduction but without making the photo noticably blurry) // Set the Sharpen details somewhere between 15% and 20%.
4. Click OK (follow this up with the Smart Sharpen filter for better results

***NOTE***
Some digital cameras produce what's called 'Blue channel noise,' because that's the channel where most of the noise winds up. To reduce that, click on the Advanced option which lets you reduce noise in individual channels. Click on the Per Channel tab and then from the Channel pop-up menu, choose Blue. Then, use the Strength slider to reduce noise in just the blue channel

I have had some very good results with Noise Ninja. There is a lot of control available with the program. I use it for my night sports photography demands. Most of the time the fields are poorly illuminated and I have to crank up the ISO to get a high enough shutter speed to stop the action. I have also heard that the higher end Canon cameras seem to deal with noise better than Nikon. It has something to do with the sensor. I'm an old Nikon man and have found less noise with Canon to be true.

You might also try this.....

If you have photoshop....

Open the image

Go to Image, select Mode

Select Lab Color

Go to Window, select Channels (This should show Lab, Lightness, a, b)

Select the "b" channel (your photo should turn to B&W and display a lot of the grain.)

Select Filter, Noise, Dust & Scratches

Make sure the window above the sliders named Radius and Threshold is showing the image at 100%

Be gentle with the radius...a little goes a long way 1 or 2 maybe 3. The grain should blend into the more solide areas of the image, generally the shadows.

I then select the "a" channel. I select filter, Noise, Dust & Scratches. This shouldn't require as much radius perhaps half of the number used on the "b" channel.

You should adjust the radius until you notice the grain "disolve" .

Click on the Lab window to see the photo again in color. If it is satisfactory, go back to Image, Mode...RGB to return to a standard output format.

There are many ways to reduce noise.....I'm sure there are faster and more controlable methods but it does work and you can create an action and a droplet to do the work in a hurry.

Hope this helps

If you can, opt to use a flash and lower your ISO. if you have to shoot available light in low light situations, you're almost inevitably going to get some noise. Make sure your F Stop is down to about 2.8, slow your shutter speed, but not too much.

If you have Photoshop, you can use the despeckle tool under filters to help elliminate some of the noise.
